Appreciate any help on the following:

Is it correct to say that when we use 1). Alternate Braking WITH antiskid, we use the yellow hydraulic system and can make as many brake applications as we require at any pressure using the foot pedals.

When we use 2). Alternate Braking WITHOUT antiskid, we lose yellow hydraulic and we must use accumulator 1000psi, 7 applications max.

If this is the case, why does antiskid determine if we have to use accumulator or not. why can't we still have yellow accumulator pressure for braking even if we have no anti skid (inop) for example?

To put it simple, I understand the Normal Braking system/principle and I understand the Parking Brake application. I just don't fully understand during Alternate Braking, when are we to use 7 apps (accumulator pressure) and when do we not need to, and why.

Appreciate your feedback.

Thanks guys,
